TMS320F28P550SJ: Libraries only available in eabi (ELF) output format, but COFF needed.

Hi,

Our expert on this matter is out of office until early January. Please expect a delayed response.

Hi Gabriel,

is there a particular reason to want to use COFF project output format? Please note we encourage our customers to migrate applications to EABI for systems that are actively being developed.

if you’re not sure how to migrate to EABI from COFF, please check out this migration guide: https://software-dl.ti.com/ccs/esd/documents/C2000_c28x_migration_from_coff_to_eabi.html

it has useful information about the migration performance of EABI and steps to migrate.

Regards,

Ozino

Hi Ozino,

We have specific requirements related to variable addressing that align better with the COFF format.

Gabriel

Hi Gabriel;

If you experience the same eabi→coff problem after every C2000Ware update as we do and need coff output, proceed as below:

1. Import the driverlib project (as .lib) into CCS for your µController (e.g. → C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f28p55x\driverlib)

2. In 'Project Properties' change the output format to coff

3. Rebuild project → The new output (driverlib.lib) will be in coff format

Good luck

Hi Ibrahim,

In general the project is compiling and I already recompiled driverlib as coff. This is not the problem.

However, from what I found in the documentation of CLAmath (CLA_MATH_LIB_UG.pdf in C:\ti\c2000\C2000Ware_X_XX_XX_XX\libraries\math\CLAmath\c28\docs), CLAmath needs separate libraries, which are mentioned in my original question.

For my device CLA Math library is present in the CLA Data ROM and I would like to use that.

Kind regards 

Gabriel

HI Gabriel,

Thanks for the additional information. Please allow us some time as we reach out to the ROM team to gather more information about the COFF versions of the library. 

Regards,

Ozino

Hi Ozino,

Just checking if there are any updates from the ROM team.

Best regards,
Gabriel

Hi Gabriel,

Still waiting to hear back from the team. I've gone ahead and CC'ed them on the post for their awareness. I'm following up with them offline.

Regards,

Ozino

Hi Gabriel,

I have heard back from our ROM team and I have the library to share with you. It will be publicly be available in the next C2000Ware release. 

Hi Ozino,

Thanks for the good news. Could you please send me the library? I assume you have access to my email address

Kind regards 

Gabriel

Hi Ozino, 

Thank you for the files. 

Can you please send F28P55xCPU1_BootROM_Symbols_fpu32.lib in coff format aswell ?

Gabriel

Hi Gabriel, 

Let me get back to the team to generate the necessary libraries. Thanks!

Regards,

Ozino

Hi Gabriel, 

Please find attached the necessary libraries. Thank you for your patience!

F28P55xCPU1_BootROM_Symbols_COFF.lib

F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib

Please let me know if you need any further help!

Hi Ozino

It seems like the libraries are not compatible with the cla2_math_library_datarom_fpu32.lib. From the error messages I receive, I think cla2_math_library_datarom_fpu32.lib uses vcrc while F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib uses vcu2

If i choose VCU support vcrc in my my main project I get this error:

error #16004-D: file "../lib/F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib<F28P55x_ROM_out__GPIO_setAnalogMode_tmp.obj>" has a Tag_VCU attribute value of "2" that is different than one previously seen ("3"); combining incompatible files

and with VCU support vcu2 i get this error

error #16004-D: file "../lib/cla2_math_library_datarom_fpu32.lib<CLAsincos.obj>" has a Tag_VCU attribute value of "3" that is different than one previously seen ("2"); combining incompatible files

Apart from that i get errors about redefined symbols in driverlib.lib now:

error #10056: symbol "_GPIO_setAnalogMode" redefined: first defined in "../lib/F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib<F28P55x_ROM_out__GPIO_setAnalogMode_tmp.obj>"; redefined in "../lib/driverlib.lib<gpio.obj>"

Hi Gabriel,

Thank you for the information. I've sent your question to the bootROM team to clarify and regenerate any necessary libraries. Thank you for your patience.

Ozino

Hi Gabriel,

Thank you for your patience. The team has generated new binaries. Please confirm if these work on your system.

Ozino

Hi Ozino,

is it possible that those libraries are now compiled for vcu2 and f28p55 needs vcrc?

Kind regards Gabriel

Hi Ozino,

Thank you. Now only the errors about the redefined symbols remain. In the documentation nothing about this is mentioned. Does this really need to be in the precompiled library? 

error #10056: symbol "_GPIO_setAnalogMode" redefined: first defined in "../lib/8461.F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib<F28P55x_ROM_out__GPIO_setAnalogMode_tmp.obj>"; redefined in "../lib/driverlib.lib<gpio.obj>"

Hi Ozino,

Thank you for your response. 
I believe the libraries are not compatible yet. In my understanding the error messages I posted before tell us, symbols are defined in 8461.F28P55xCPU1_BootROM_Symbols_fpu32_COFF.lib and driverlib.lib

If I am supposed to actively remove functions in the driverlib I would be thankful for instructions.

I can confirm, the driverlib is not rebuilt in the project and the precompiled .lib file is used as confirmed in the .map file.

Regards,

Gabriel

Hi Gabriel,

You shouldn't make have to remove libraries from driverlib. Can you confirm if you added the same bootROM libraries to an empty or led blinky project that you are observing the same compilation errors. If not, then I suspect something may be amiss with your project.

Can you confirm what version of the C2000Ware you are including in your project?

Regards,

Ozino
